P87LPC761 is a 16-pin packaged microcontroller produced by Guangzhou Zhouligong Single Chip Microcomputer Development Co., Ltd. It is suitable for applications requiring high integration and low cost, and can meet various performance requirements. The microcontroller uses an accelerated 80C51 processor structure, with instruction execution speed twice that of the standard 80C51 CPU. It features an operating frequency of up to 20MHz, 2K bytes OTP program memory, 128 bytes of RAM, 6 keyboard interrupt inputs, 4 interrupt priority levels, and more.
This manual describes the ZLG P87LPC761 microcontroller, a 16‑pin device aimed at high‑integration, low‑cost applications. It covers the CPU core, memory organization, power options, and peripheral features.
Key sections include the feature list, ordering information, pin‑out diagrams, special‑function registers, reset and power control, analog comparator configuration, and bus interface details. The document also provides package dimensions for both DIP and TSSOP versions. This manual is written in Chinese.
